Optimizing Rehabilitation for Phantom Limb Pain Using Mirror Therapy &

Status Active, not recruiting

Clinical Trial Summary

This is a two-site study that explores the effects of mirror therapy and transcranial Direct Current Stimulation (tDCS, Soterix ©) in a randomized factorial controlled trial in which patients will be assigned to one of four groups: active tDCS and active MT; sham tDCS and active MT; active tDCS and sham MT (which consists of using a covered mirror for the therapy); and both sham tDCS and sham MT (covered mirror).

Clinical Trial Description

Phantom limb pain (PLP) belongs to a group of neuropathic pain syndromes that is characterized by pain in the amputated limb. Rehabilitation for chronic pain involves a structured treatment plan targeting all dimensions of the pain experience, and should include a comprehensive interdisciplinary approach that allows patients to receive the most benefit according to their needs. As in other chronic pain syndromes, chronic Phantom limb pain (PLP) is often difficult to treat; showing to be resistant to classical pharmacological and surgical treatment approaches. In this context, we hypothesize that novel treatments of PLP need to target specific neural networks associated with this maladaptive plasticity. Transcranial direct current stimulation (tDCS,Soterix ©) is a powerful and non-invasive technique of brain stimulation that is known to significantly modulate plasticity and alleviate chronic pain in various syndromes. device for this trial. This study usiGiven tDCS underlying neural mechanisms, it is critical to use a multimodal approach to treatment - using both tDCS and behavioral therapy simultaneously. In this case, an ideal therapy is mirror therapy (MT). Recently, we showed that anodal tDCS can induce a selective short-lasting relief from PLP, and repeated applications of anodal tDCS induces long-lasting analgesic effects. These preliminary results show that tDCS may be a promising rehabilitative tool for the management of chronic PLP. This neurorehabilitation technique is commonly used in PLP, and is designed to modulate cortical mechanisms of pain by performing movements using the unaffected limb in front of a mirror. We propose to carry out a mechanistic, factorial, randomized controlled trial to evaluate a novel rehabilitation approach combining tDCS and MT in PLP patients. We aim to compare the brain changes before and after treatment in order to study the mechanisms underlying PLP. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
